regexec from regex.h Segmentation fault

the below program is working in Suse and not working on Cent 5:
can any body have the solution ?

#include <regex.h>
#include <stdlib.h>
#include <stdio.h>

int main(){

char cool[] = "http://www.cnn.com:80/wowsers.html";
regex_t test_reg;
regmatch_t matches[3];
int num_matches;
int success = regcomp(&test_reg, "http://([^/]*)(/{0,1}.*)",
printf("regcomp success = %d\r\n", success);
success = regexec(&test_reg, cool, num_matches, matches, 0);
printf("regexec success = %d\r\n", success);
printf("overall match start index = %d\r\n", matches[0].rm_so);
printf("overall match end index = %d\r\n",
printf("first match start index = %d\r\n", matches[1].rm_so);
printf("first match end index = %d\r\n", matches[1].rm_eo);
printf("second match start index = %d\r\n", matches[2].rm_so);
printf("second match end index = %d\r\n", matches[2].rm_eo);


OUTPUT on SuSE(10.2):
regcomp success = 0
regexec success = 0
overall match start index = 0
overall match end index = 34
first match start index = 7
first match end index = 21
second match start index = 21
second match end index = 34
OUTPUT on Cent(5):
regcomp success = 0
Segmentation fault

regex.h are same on both machine.

ldd ./regex ( on Cent 5 )
linux-gate.so.1 = (0x00a43000)
libc.so.6 =/lib/libc.so.6 (0x00110000)
/lib/ld-linux.so.2 (0x0093c000)
glibc-devel-2.5-12 (rpm -qf /usr/include/regex.h)
ldd ./regex ( on SuSE 10.2 )
linux-gate.so.1 = (0xffffe000)
libc.so.6 =/lib/libc.so.6 (0xb7d8c000)
/lib/ld-linux.so.2 (0xb7ee9000)
glibc-devel-2.5-25 (rpm -qf /usr/include/regex.h)

You are expected to say how big the matches array is. This is not
really on-topic here. Further problem should go to
comp.unix.programmer since this is a POSIX interface.
